namespace AddNewRow {
    public class DemoViewModel : INotifyPropertyChanged {
        BindingList<TestData> itemsSource;

            ItemsSource = GenerateData();
        }
        BindingList<TestData> GenerateData() {
            BindingList<TestData> list = new BindingList<TestData>();
            for(int i = 0; i < 5; i++) {
                list.Add(CreateTestData(Guid.NewGuid().ToString(), "text2 " + i, "text3 " + i));
            }
            return list;
        }

        TestData CreateTestData(string text1, string text2, string text3) {
            return new TestData() {
                Text1 = text1,
                Text2 = text2,
                Text3 = text3
            };
        }

            get { return itemsSource; }
            set {

                NotifyPropertyChanged("ItemsSource");
            }
        }

        public void AddNewRow(string text1, string text2, string text3) {
            ItemsSource.Add(CreateTestData(text1, text2, text3));
        }

    public class TestData {
        public string Text1 { get; set; }
        public string Text2 { get; set; }
